Hey, recently I noticed that there is a weird sphere white bubble outgrowth or wart on one of my Bosemani Rainbow's lip. I don't think its cottonmouth as it is pretty smooth rather than "cottony" shape. The sphere seems to have an attachment to the lip through a small tube structure and the sphere is attached to the end of the tube growth...if that makes anyways. I have some pictures here to help. If someone could identify it and how to treat...I would really appreciate it and thanks for the time.

Water condition is pretty clean as I do weekly water changes with 15 plants in a 25g. No other fish exhibits these symptoms and the the rainbow seems to be acting normal.

Separate the fish. It is easily bacterial in nature especially if it bursts.

What are the water parameters?
Have you observed this fish getting an injury before?
Once separated, try to dose a teaspoon per gallon of salt in the tank and add the second set in the next 12 hours. Stick to 0.2% dose for now. See if this helps improve the cyst after a few days.

I'm ready for the pressure.

Give it a week treatment. Add a teaspoon per gallon of sodium chloride followed by another set of same dose in the next 12 hours. We'll stick to 2 teaspoons per gallon total dose for now. Make sure salt does NOT contain yellow prussiate of soda. Aquarium salt, pickling salt and rock salt work.

Lupin, I just got around with getting the quarantine tank supplies, but I noticed that the cyst has fallen off and the lip is a bit still white to a point where I wouldn't have noticed if there was a problem. Should I continue and move the fish into the tank and do a week salt treatment still to promote healing? Thanks.
